QueueArray

gst.QueueArray.QueueArray is an object that provides standard queue functionality based on an array instead of linked lists. This reduces the overhead caused by memory management by a large factor.

Constructors

this this(GstQueueArray* gstQueueArray, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(uint initialSize): Allocates a new gst.QueueArray.QueueArray object with an initial queue size of initial_size.
this this(size_t structSize, uint initialSize): Allocates a new gst.QueueArray.QueueArray object for elements (e.g. structures) of size struct_size, with an initial queue size of initial_size.

Destructor

A destructor is present on this object, but not explicitly documented in the source.

Members

Functions

clear void clear(): Clears queue array and frees all memory associated to it.
dropElement void* dropElement(uint idx): Drops the queue element at position idx from queue array.
dropStruct bool dropStruct(uint idx, void* pStruct): Drops the queue element at position idx from queue array and copies the data of the element or structure that was removed into p_struct if p_struct is set (not NULL).
find uint find(GCompareFunc func, void* data): Finds an element in the queue array, either by comparing every element with func or by looking up data if no compare function func is provided, and returning the index of the found element.
free void free(): Frees queue array and all memory associated to it.
getLength uint getLength(): Returns the length of the queue array
getQueueArrayStruct GstQueueArray* getQueueArrayStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
isEmpty bool isEmpty(): Checks if the queue array is empty.
peekHead void* peekHead(): Returns the head of the queue array and does not remove it from the queue.
peekHeadStruct void* peekHeadStruct(): Returns the head of the queue array without removing it from the queue.
peekNth void* peekNth(uint idx): Returns the item at idx in array, but does not remove it from the queue.
peekNthStruct void* peekNthStruct(uint idx): Returns the item at idx in array, but does not remove it from the queue.
peekTail void* peekTail(): Returns the tail of the queue array, but does not remove it from the queue.
peekTailStruct void* peekTailStruct(): Returns the tail of the queue array, but does not remove it from the queue.
popHead void* popHead(): Returns and head of the queue array and removes it from the queue.
popHeadStruct void* popHeadStruct(): Returns the head of the queue array and removes it from the queue.
popTail void* popTail(): Returns the tail of the queue array and removes it from the queue.
popTailStruct void* popTailStruct(): Returns the tail of the queue array and removes it from the queue.
pushTail void pushTail(void* data): Pushes data to the tail of the queue array.
pushTailStruct void pushTailStruct(void* pStruct)
setClearFunc void setClearFunc(GDestroyNotify clearFunc): Sets a function to clear an element of array.
